, fective and practical means of incineration in conjunction with the main chimney of the dwelling A. feature of the invention resides in the circular construction of the combustion chamber of the incinerator, preventing air pockets and providing a combustion and reception chamber for the refuse, which percauses complete incineration of the refuse and overcomes the disadvantages-where the incinerator is of a complicateddesign and wherein the walls of the incinerating chamber are formed with angular pockets instead of the circular dome-like construction which I have provided in my design of incinerator. It is a well-recognized fact that the circular combustion chamber is more 'operable'by the incineration-which ordinarily burns continuously in a large flat or dwelling with sufiicient heat to operate the coil; and I further provide a gas or oil heater in connection with the water coil which can be operated to heat the water either in conjunction with the operation of the incinerator or independently.

In my incinerator the coil is designed to be positioned in the circular dome out of line with the flue opening of the chimney proper to permit the refuse to pass free of the water coil and gas heater. This is an important feature of my invention. The invention includes a grate set up in a manner to provide means for rotating the same 1824. Serial No. 728,442.

above the ash bed and set into the circular design of the fire pot with a peculiar construction and flange holding means which is associated with the fire brick in the most effective manner. r

The features and peculiar construction; together with other objects and advantages of my incinerator will be more fully set forth in the following specification and claim: K

Figure l is a side, sectional elevation of my incinerator and its connecting chimney as it would appear in use. 1 v

Figure 2 is a section on the line 22 of Figure 1.

Figure 8 is a section on the line 3-3' of Figure l.

Figure at is a section of a portion of the operating grate of the incinerator.

Figure 5 is a section of the lower portion of the incinerator illustrating the grate. to-, gether with the clean-out door in 'the ash pit and the door into the fire compartment of the same. A

My incinerator is formed with the combustion chamber 10, which is of a circular construction, in which the grate 11 is po' sitioned in a manner so that it can be cperated to dump the ashes into the ash pit 12 when desired by rotating the grate as illustrated in Figure 4. The ash pit is provided with 'a clean-out door 13 of ordinary construction, while the fire chamber or combustion compartment 11 is provided with a door let so that when. it is desired the fire chamber can be reached through the door 14.

The grate-11 is of a circular construction with the holding lugs 15 formed on one side, which rest upon the shoulder 16 in the incinerator base. In the construction of the grate illustrated in Figures 3 and 5 an annular flange member 17 is built into the base B of the incinerator A with the fire brick lining 18 built up and resting upon the horizontally extending annular lip 19 of the flange 17. This construction provides a grate for the incinerator A of a practical nature and of suitable strength so asto carry the load ordinarily required of an incinerator grate.

The grate 11 in Figure 1 is of a similar construction excepting: tl at the east flange 17 is not present and the lugs J? of the grate rest upon the metallic ring; 20. which extends horizontally and upon which the tire hriclt lining; re at the bottom of the incinerator. The shaker rod ill operates the grate in a rotary movement to dump the same.

The lire hrirlt lining I8 is huilt up-inlo the cylindriial portion t, of the incinerator A to meet the dome portion ll of the same. At the (lOIllO lho incinerator is built into a conical formation and the lire hriclc l8 follow the inner contour of the same up to the main chimney E, which carries the ordinary flue lining as a protective medium for the lining of the chimney. The dome l) is reinforced by metal rings 22 which are set in the brick walls of the dome in a manner so as to reinforce the same and give, the necessary strength to provide a suitable base for the upper portion of the chimney I). This is an important feature of my incinorato' as it permits the conical dome to he made in a manner so that the w ll is not out of proportion with the hase portion and to conform and blend into the formation of the chin'iney proper.

The incinerator A is designed so as to form a part of the chimney l3 and used for the smoke pipe or chimney of the furnace by introducing in the dome the regu lar furnace smoke pipe 23 of ordinary construction. leading from the heating plant or :t'urnace used in the dwelling.

\Vithin the coniliiustion chamber of the incinerator A. I position a *ater coil F which is provided with an inlet pipe 524: and an outlet pipe 525. so that; water can circulate freely through the coil and the pipes E l: and 2?; are connected with the hot water piping of the dwelling in the ordinary well known manner. not shown in the drawings. Directly beneath the coil ll I provide a circular gas or oil burner G which is designed to heat the coil F when it desired and the shut oil valve 26 of which placed at a distance from the in ciuerator hody so as not to interfere with the incineratino operation when the gas or oil. humor is not desired. The plug: 97 closes the opening in the side of the incinerator wall and when it is desired to light the hurncr (i this pine is removed and 11 liillllt intrrulured through the plug opening in a manner so as to properly igrnile the. hurner (l.

A. feature of the. invention resides in placing the coil l. which is circular in construction. out of line with the inside contour of the llue lining; of the chimney as indicated by the dotted lines Q? in l ieure l of the drawing. In this manner the refuse which is to he incinerated can he introduced into the chimney E and it will pass directly neaegaor through the coil i and on lo the grate 1.1. without iuterteriiur with the coil l and the burner (.l. V

in a, flat or lare e dwelling: where a great. deal. of refuse is rollectial and introduced into the incinerator A the same will co11- tinue to hurn praetieall. v all o! the time. Thus the coil l facilitates hot water being maintained for the [lat so as to obviate the necessity of having a separate hot water heater. la. connection with the coil F the incinerator can he tired hy suitable fuel upon the grate 11 which kept burning and which incineraies the refuse introduced into it; as that as it .is dumped into the incineratw ing; chamber. thus requiring; but one heating medium for the incineration and for the hot water system. This is quite a saving in the summer months in the consumption of fuel in an a nirtn'ient or dwelling where the incinerator is employed.

The gas burner (i can he euuployed when the incineration is not sul'iicient to heat the "alter or when no iiuiinoration in process. It also obvious that the self same construction of the gas burner (i can he used to introduce a liquid fuel such as coal oil or other suitahle cornhtistihle liquid fuel which is sprayed onto the refuse, to he incineratcd and thus the incinerator A will accomplish a very desirable result. This has proven to he a very satisfactory means of consuming; large quantities of garbage or refuse which is constantly being; introduced into the incinerator A. The spray of coal oil or liquid fuel forms a. suitable means of combustion which has a. great deal of heat units. tending to consume the refuse ver rapidly so that the consuni frtion of the same is complete. even though the refuse is wet when introduced into the incinerator A. This is an important feature of my invention and serves to provide a suitable heat inn means for the water coil F. The effective operation of my incinerator is apparent and the. simplicity of construction is a marked advantage in thooporation and cost of construction of my incinerator. The circular fire pot or conihustion chamber, together with the conical dome n'evcnt any pockets, and allow a. clear uninterrupted draft which is highly important in the successful operation of a device of this nature, where the inciiunator forms a part of the chimney for the dwelling to load the. smoke from the heating furnace and so that the drafts are unohstructed.

In accordance with the patent statutes I have descrihcd the principles of oporatitni of my invention. together with the apparatus which I now consii'ler to represent the host embodiment thereof. hut I desire to have it understood that the construction shown in the th'awines only illustrative, and that. the invention can he carried out by other lift means and applied to uses other than those above set forth Within the scope of the fol:

lowing claim.

I claim: 7

An incinerator including a combustion chamber, a chimney connected to said combustion chamber adapted to receive refuse therethrough and to carry 01f the gases from i said combustion chamber, an opening in said chimney to receive refuse into said inciner- 10 refuse introduced therein to consume en-'1 tiroly the refuse in said incinerator.
